A contractor quoting a central AC install in Halifax County has to account for what the equipment will actually face here, not just the square footage of the house. 107 severe weather events were recorded in Halifax County, North Carolina between 2015 and 2024. At that rate, severe weather is a standing condition, not an occasional event, and a system sized or installed to a generic standard will be working against a climate that regularly pushes it hard. Duct layout, equipment capacity, and component ratings all get weighed against what this county asks of a system year after year.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow, load, and routing that a new central AC system does not share. Half the homes in Halifax County, North Carolina were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to assess what is already in the walls before the equipment choice means much, because duct runs that worked for older systems often need modification to deliver what a modern unit expects. Electrical service is the second check. Together, those two things in the existing house set the real scope of the job.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and houses the evaporator coil and blower that pulls air through the system. These two units are the core of what a contractor sets in place.
A refrigerant line set runs between the indoor and outdoor units, carrying refrigerant through insulated copper tubing that passes through the wall. The thermostat mounts on an interior wall and gives the homeowner control over the whole system. A condensate drain line also runs from the air handler to carry away the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of your home.

What the Installation Actually Looks Like
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.

Severe Weather Events in Halifax County
Weather puts real demands on cooling equipment, and those demands are specific to where the equipment runs. A central AC system installed in Halifax County is sized and built to handle local conditions, so what the weather does here is part of how a contractor thinks about the work.
